Concept explainers
(a)
Interpretation:
- The resonance contributors for the following species has to be predicted.
Concept Introduction:
Resonance Contributor: The appropriate structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.
Resonance hybrid: the actual structure with delocalized electrons is called a resonance hybrid.
b)
Interpretation:
- The most stable resonance contributors for the given compounds has to be predicted.

- Ranking resonance structures Rank the resonance structures in each row of the table from major to minor. For example, in the first row, select (major) for the major resonance contributor. If two or more structures in the same row contribute equally, rank them equally by selecting the same number. X. :ö: :ö: ータ H. Rank) (Rank) H. H. H. H. H.
